Common bird index

The indicator is an aggregated index integrating the population abundance and the diversity of a selection of common bird species. Three groups of bird species are presented in this indicator: farmland specialists (39 species), forest specialists (33 species) and all common bird species (farmland species, forest species and a further 91 species).Rare species are excluded.

Contribution to the green economy:

Higher values of the index represent higher population abundance and diversity of a selection of common bird species associated with specific habitats, which is therefore beneficial to environmental sustainability,

Potential misinterpretation:

The indicator aggregates information about populations and diversity of several species but does not indicate the health of a particular species or a particular habitat. Indicators for these aspects should also be considered.
